what do you think this is? rang nhs direct and they weren't very helpful and out of hours doc has no appointments

ds has been poorly since tuesday. he's had a temperature although that seems to have gone now, sore throat (well i think he has - he won't eat and isn't drinking much but he isn't able to tell me if it hurts so can't be sure), doesn't want any clothes on (not sure if this is cos he is hot or possibly itchy??), diarrhea, bad cough and his ear hurts cos he keeps pulling on it. today he's come out in a rash aswell although it is only on his chest and tummy.

nhs direct said it could be a viral rash or it could be measles and to just keep an eye on him. he hasn't been ill for longer than a week so perhaps that's why they thought he didn't need to see a doctor?
